Chloridazon is a selective organochlorine herbicide that belongs to the group of pyridazinone compounds. It acts as systemic soil and leaf herbicide by inhibiting the photosynthesis process. It is used for pre-plant, pre-emergence, and early post-emergence, to control annual broad-leaved weeds, sugar beets, and red table beets.
Chloridazon is not authorized for use in the European Union as per the European Council Directive 91/414/EEC concerning the placement of plant protection products on the European market. Maximum residue levels (MRLs) have been set according to Reg (EU) 2016/1015 for Chloridazon for various products of plant and animal origin from 0.05 to 5 mg/kg.

Application
Chloridazon may be used as certified reference material for the following:
- To examine the effects of chloridazon on the response of the frog neuroepithelial synapse to electrical stimulation and the basal values of the bioelectric parameters of the frog skin
- To study the transformation of n-chloridazon in a fixed bed bioreactor for verification of microbial degradability at different dosed contamination levels and govern the adaptation processes
- To investigate the effects of thermal and acid treatments on the sorption properties of a natural sepiolite by evaluating the adsorption process of chloridazon herbicide
- To prepare and characterize controlled release formulations of chloridazon using biodegradable polymers like ethylcellulose and lignin
- To investigate the potential use of lignin-based controlled release formulations (CRFs) to control release rate and leaching of metribuzin and chloridazon in soils
- To synthesize a meso-sorbent silica/polyaniline (MSNPs/PANI) composite for the removal of the chloridazon pesticide from the aqueous solution

A sampling campaign was carried out for n-chloridazon (n-CLZ) and its degradation product desphenyl-chloridazon (DPC) in the Hesse region (Germany) during the year 2007: a total of 548 environmental samples including groundwater, surface water and wastewater treatment plant (WWTP) effluent

Chloridazon is a widely used organochlorine herbicide. In order to evaluate its perturbing effect on cell membranes it was made to interact with human erythrocytes, frog adrenergic neuroepithelial synapse and molecular models. These consisted in multilayers of dimyristoylphosphatidylethanolamine (DMPE) and
